Introducing LEEDv4

The U.S. Green Building Council is raising the bar for sustainable construction with the launch of the Leadership in Energy and Environmental Design version 4 (LEEDv4) rating system. The new system streamlines the arduous LEED certification process, updates previously established guidelines to match more recent building codes, offers a new breakdown of standards by sector, and encourages collaboration among the architects, builders, and others involved in the construction and design process. Projects can obtain LEED 2009 certification until June 1, 2015, when LEEDv4 becomes the only rating system available.
